None of the above. Question 10 Purposive sampling is: The process of selecting a number of individuals (a sample) from a population, preferably in such a way that the individuals are representative of the larger group from which they were selected. Methods designed to select a representative sample by using chance selection so that biases will not systematically alter the sample. A nonrandom sample selected because prior knowledge suggests it is representative, or because those selected have the needed information. Refers to conducting a study again; the second study may be a repetition of the original study, using different subjects, or may change specified aspects of the study.
